T0 @ZZ zul/2,0111, it may concern:

Beit known that I, EUGENE R. EDsoN, a citizen of the United States ot' America, residing at Cleveland, 1n the county of Cuyahoga and State of Olne, have invented certain new and useful Improvements in Rendering or Reduc-V ing Apparatus; and I herebydeclare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in rendering or reducing apparatus suitable for use in the production ot' oil and fertilizer from fish-waste, garbage, and other material, and pertains more especially to apparatus not only suitable for extracting oil from the said material by the treatment of the material with a volatile solvente-such, for instance, as napl thabut well adapted for eliminating from the mass all traces or' naphtha, gases, noxious odors, and moisture after draining or removing from the mass the extracted oil and the solvent mixed with the said oil, so as to render the residue suitable for use as a fertilizer..

The primary object of this invention is to provide simple and inexpensive apparatus capable of efciently and speedily reducing' material of the character indicated.

Vith this object in view and to realize other advantages hereinafter appearing, the invention consists in certain features of construction and combinations of parts, hereinafter described, and pointed out in the claims. K

In the accompanying drawings, Figure I is a side elevation, largely in centralfvertical secn tion, of apparatus employing my invention. Figs. II and III are vertical sections in detail, illustrating a portion et the means employed in distributing steam and air within the body of material undergoing treatment. Fig. IV is a top plan in section on line IV IV, Fig. I; but the perforated false bottom is omitted in Fig. IV. Fig. V is a top plan in section on line VV, Fig. I; but several oi the sections of the perforated false bottom or' the tank ot' the apparatus are omitted in Fig. V to show several of the perforated branching-out sections below the said bottom. Fig. VI is a top plan, largely in section, oi' one of the duid-distributing sections g. Fig. VIIis a top plan, largely in section, of one oiZ the fluid-distributing sections u. Figs. II, III, VI, and VII are drawn on a larger scale than the remaining iigures.

Referring to the drawings, c designates a normally closed tank which is cylindrical and provided at the top and centrally, as shown in Fig. I, with a charging-aperture 10, at which the material to be treated is introduced into the tank upon opening or removing the suitably-applied cover 12,` which normally closes the said aperture.

The tank c, a short distance above its bottom 1li and at one side, is provided with a lateral aperture 13, which is closed by a suitably-applied door or cover 15, upon removing which access is had to the interior of the tank for repairs and cleaning and for removing from the tank any residue remaining therein ai'ter the treatment of material. The bottom 1/1 is depressed at its central portion, as at 16, to form a receptacle which has its bottom provided, at one side of its central portion, with a hole 17 extending vertically therethrough. The bottom 14 declines toward the receptacle 1G, so as to facilitate the flow of oil extracted from material treated within the tank into the said receptacle, whence it Hows through the hole 17, where it is received by a reservoir or pipe. (Not shown.) A valved pipe I for supplying naphtha or solvent to the chamber of the tank is arranged to discharge into the upper portion oiI the said chamber and has its valve 18 normally closed.

rihe tank (t is provided, atits upper end, with a vapor-conducting pipe or line c, which is connected with the receivingend or inlet oi' a suitably-operated pump or device (l, adapted when operating to create suction within the vapor-outlet c, and consequently within the chamber ot' the tank a.

A pipe c, which has a normally closed valve 20, is employed to conduct steam or air into the lower portion oi the chamber of the tank c and extends in under a centrallyedepressed portion 16 of the bottomv 14 and there discharges through a hole Q2, with which the bottom of the said portion 16 is provided,

Vnal annular flange 24, which is secured, preferably, removably by means of bolts andnuts, as at 25, to the said bottom. rlhe upper portion of the chamber 23 is annular and liares upwardly, as at 26, and a group of branchingout perforated interchangeable pipe-sections g are arranged in a horizontal plane and radially of the bottom 14 at suitable intervals around the pipe-section f. The pipe-sections g rest, at their outer ends, upon the bottom 14 and communicate, at their inner ends, with the upper end of the upwardly-flaring portion 26 of the interior chamber 23 of the multiplepipe coupling f. The extension of the pipe e to the bottom of the tank below the inner ends of the pipe-sections g and the discharge of the said pipe e into the said i pipe-sections g through the multiple-pipe coupling f renders the construction simple and inexpensive and convenientin the assemblage and removal of parts.

Each pipe-section g comprises, preferably, a central member 27, arranged radially of the chamber of the tank a and extending from the coupling' f outwardly into close proximity to the surrounding wall of the said chamber. The said member 27 is provided, internally, with a passage-way 28, which extends longitudinally of the said member. The said passage-way 28 communicates at the inner end of the said member 27 (see Fig. Il) with a discharge-aperture 30, formed in the top wall of the chamber 23 of the coupling f# that is, the chamber 23 discharges through holes 30, formed in the top wall of the chamber, into the pipe-sections g, and as many apertures or holes 30 as there are pipe-sections g are provided.

A pipe-section is shown detached in Fig. Vl, and it will be observed that the central member 27 of the said section has several concentrically-arranged hollow arms 32 extending from and laterally of the said member 27 in one direction and several concentricallyarranged hollow arms 33 extending' from and laterally of the said member 27 in the opposite direction, that the passage ways 34, formed within and extending'. longitudinally of the said arms, are closed at their outer ends, as at 35, and communicate, at their inner ends, with the passage-way 28 ofthe aforesaid central member 27, and that the said member 27 and its arms 32 and 33 have perforations or oriiices 36 for discharging the fluid conducted to the said passage-ways from the coupling f into the chamber of the tank a. Each pipe-section g is provided externally at the inner end of its member 27 with a lug 38, (see Fig. TL) which rests upon the upper end of the coupling f. Each section g is suitably supported, therefore, within the lower portion of the tank and is provided with numerous laterally-discharging orifices 36, arranged at suitable intervals along the passage-ways formed in the pipe-section g.

A perforated false bottom is arranged over and in close proximity to the perforated pipesections g and is composed of several generally triangular perforated sections it, which are arranged in a horizontal plane radially of the tank withtheir wider ends next to the surrounding wall of the chamber of the tank. The sections L are held downwardly at their inner ends over the couplingf by a bolt or screw Zr, a washer l, and collar m, as shown very clearly in Fig. II. The bolt or screw is arranged vertically and engages a correspondingly screw-threaded hole 42, formed in and centrally of the upper end of the coupling f. The collar m embraces the shank of the bolt or screw and rests upon the upper end of the coupling f, and the lower end of the said collar is enlarged diametrically to form an upwardly-facing annular shoulder 43, which constitutes a seat for the inner ends of the sections 7L of the false bottom. The sections L at the said ends have downwardlyprojecting ianges 44, which rest upon the the medium of the flanges 44 of the sections /L and the washer m, and that the removal or withdrawal of the bolt or screw /cdetaches the coupling f and false-bottom sections /L for repairs or other purposes.

The material which is to be treated within the tank a rests upon the perforated false bottom, and the oil or liquid extracted or flowing from the said material passes through the perforations of the said bottom downwardly to and upon the tank-bottom 14 andthence gravitates down the latter to the discharge opening or outlet 17. A valved steamsupply pipe a and a valved air-supply pipe 0, arranged externally of the tank a, are connected and communicate with the pipe c. The valve 45 of the pipe a and the valve 46 of the pipe 0 are normally close and obviously air or steam is conducted to the pipe e, and consequently to the pipe-sections g, within the tank a upon opening` the valve 20, according as the valve 46 or the valve 45 is opened.

Obviously steam discharged from the pipesections g passes upwardly into any body of material undergoing treatment upon the false IOO IIS

bottom and is instrumental in heating the said material and assists in stirring the material and facilitatesthe passage of vapor and gases from the material to the vapor-outlet c. Any air discharged from the pi pe-sections g is instrumental in stirring or disintegrating the body of material undergoing treatment within the tank and participates in the elimination and passage of vapors and gases from the body of said material.

rjhe perforated false bottom practically separates the body of material from the pipesection g, and the liability of any clogging of the discharge orifices or perforations of the said pipe-sections g by the said material is re* duced to a minimum. It will be observed also that the arrangement of the pipe-sections g insures a distribution of the fluid discharged therefrom through the entire mass'of material.

A pipe p, which has a normally closed valve 47, is employed to conduct steam or air into the chamber of the tank a above the discharge-aperture 13 of the tank (see Fig. l) and comprises a vertical pipe-section 50, arranged within and centrally of the said chamber and connected, at its upper end, by an elbow 52 with a horizontally-arranged pipe-y section 53, which extends to the outside of the tank and is there connected by an elbow 54 with a pipe-section 55, which is connected with the pipes a and o and has the valve 47.

The pipe p is adequately supported within the chamber of the tank a bya pair of beams or bars r, which are arranged horizontally within and extend transversely of the said chamber at opposite sides, respectively, ofthe upper end of the pipe-section 50 and are supported in any approved manner from the tank fr, and the elbow 52 is provided with an ex' ternal annular flange or member 56, which rests upon the said bars or beams.

An internally-screw-threaded sleeve s, as shown very clearly in Fig. III, engages corresponding serew-threads formed externally of and upon the lower end of the pipe-section 50. The sleeve S is provided, at its lower end, with an external annular flange 57, which is arranged over and corresponding annular .flange 58, formed upon and externally of the upper end of a vertically-arranged multiplepipe coupling t, which is suspended from the pipe-section 5() of the pipe p, centrally of the chamber of the tank and is secured to the sleeve s removably by bolts fn, which extend through the flanges 57 and 58, and nuts y' engaging the said bolts. The pipe-coupling t is therefore detachably secured to the pipe j), which discharges at the lower end of its pipe-section 5() into the upper end of the chamber 60, formed by and within the coup ling 2 5. The lower portion of the chamber 6() is annular and flares downwardly, as at 62, and a group of interchangeable branchingLout perforated pipe-sections a are arranged in a horizontal plane and radially of the chamber Vthe coupling t outwardly into close proximity to the surrounding wall of the said chamber'. The said member 67 is provided internally with a passage-way 68, which extends longitudinally of the said member.' The said passage-way 68 communicates at the inner end of the said member 67 as shown very clearlykin Fig. Hl, with a discharge-port 70, formed in the bottom of the chamber 60 of the section -that is, the chamber 60 discharges through holes 70, formed in the said bottom, into the pipe-sections a, and as many apertures or holes 70 as there are pipe-sections a are provided.

A pipe-section a is shown in Fig. VH, and it will be observed that the central member 67 of the said section has several concentrically-arranged hollow arms 72 extending from and laterally of the said member 67 in one diw rection and several concentrically-arranged hollow arms 73 extending from and laterally of the said member 67 in the opposite direction, that the passage-ways 74 formed within and extending longitudinally of the said arms are closed at their outer ends, as at 7 5, and communicate at their inner ends with the passage-way 68 of the aforesaid central member 67, and that the said member 67 and the said arms 72 and 73 have perforations or orifices 76 for discharging the fluid conducted to the said passage-ways from the coupling' Z into the chamber of the tank a. Each pipe-section 'u is provided externally at the inner end of its member 67 with a lug' 78, (see Fig. IIL) which bears against the lower end of the coupling t; A vertically-arranged rod lw extends through the elbow 52 and centrally through the pipe-section 50 and through and a suitable distance below the coupling t, which is suitably perforated centrally, as at 66, to aecommodate the location and operation of the said rod. The rod w extends through an internally-screw-threaded [lange or member 65, with which the elbow 52 is provided, and has correspondingscrcw-threadsengagingtln'eads within the said member 65. The rod is directly supported, therefore, from the pipep and indirectly from the beams or bars r. A nut a' is arranged belowtlie coupling and engages corresponding screwtlireads formed upon the lower end of the rod '20, and acollar y is mounted upon the said rod between the said nut and the lower end of the said coupling t. rlhe lower end of the collar y is enlarg'ed diametrically to form an upwardlyfacing annular shoulder 7 9, which constitutes a seat for the inner ends of the pipe-sections a, being engaged by or extending in under the bottoms of the lugs 7 8 of the said pipesections u.

By the construction hereinbefore described it will be observed that all of the pipe-sections u are held at their inner ends up against the coupling t by the rod w and the nut w through the medium of the collar y, and that the turning of the rod fw to the extent re- Y quired in the required direction will result in lowering the said rod sufciently to cause the collar y to release the pipe-sections u.

Two arms 72 and 73 of each pipe-section u are arranged at opposite sides, respectively, of the outer end of the said section, and are hung upon the surrounding wall of the chamber of the tank through the medium of hooks or hang'ers k1 attached to the said wall. The release, therefore, of the pipe-sections u by the collar g/ will permit the said sections to swing downwardly and outwardly toward the said wall, and the said pipe-sections u are readily removable.

It will be observed that the pipe-sections u do not interfere with the feeding of material to and upon the false bottom from the aperture 10 because the spaces between the arms of the pipe-sections u afford passage for the said material.

Air or steam is conducted to the pipe p,and consequently to the pipe-sections u,upon opening' the valve 47 according as the valve 46 or the valve 45 is opened. The object of conveying steam through the pipe-sections u into the chamber of the tank a is to heat the body of material undergoing treatment, to

participate in stirring the material, and to facilitate the passage of vapors and gases from the material. Air conducted through the said pipe-sections u into the said chamber stirs the material and operates to eliminate and carry vapors and gases from the material. It will be observed also that the arrangement and construction of the pipe-sections u insure a distribution of fiuid discharged therefrom through the upper portion of the body of material.

The rod w extends upwardly into the aperture l0, where it is reachable by a wrench introduced through a screw-threaded hole which is formed in the cover l2 and normally closed by a correspondingly-threaded plug WV hat I claim isl.v In rendering or reducing apparatus, a tank provided with a vapor-outlet; several perforated pipe-sections arranged in a hori- Zontal plane within the chamber of the tank and comprising, respectively, a main hollow' member which extends from the central portion of the said chamber laterally and outwardly and has laterally-projecting hollow perforated arms in open relation with the said main member, and means for conducting fluid to the inner ends of the passage-ways formed by and within the laterally and outwardly extending main members of the said perforated pipe-sections.
